"Lost" alum
Elizabeth Mitchell has landed a series regular role on J.J. Abrams' latest television show,
"Revolution." Written by "Supernatural" creator Erik Kripke, "Revolution" explores a future where all forms of electronic technology have ceased to work. Mitchell will play the mysterious Rachel Matheson, replacing Andrea Roth, who played the role in the pilot.

Rachel is the estranged mother of Charlie (Tracy Spiridakos) and Danny (Graham Rogers), whose world is thrown into further turmoil when their father is killed by the militia and Danny is kidnapped. Charlie sets off to find her uncle (Billy Burke) to save her younger brother.

THR, who first
reported the casting, describes Rachel as "a beautiful and warm parent who's terrified of the ordeal that her children will face as they navigate the dystopian world."

"Revolution" has also cast
Daniella Alonso, who recurred on "Friday Night Lights" and "One Tree Hill." Alonso will play Nora, a freedom fighter who has turned her back on her wealthy family. Nora, who has a romantic history with Billy Burke's character, has a "lethal" streak and truly believes the world is better off without power.
